Hello Peoples!,

MAIN QUESTION: Try to give you guys as much info as i can here. picture it: Two neodymium magnets mounted perfectly above one another in a repel state, i drew up a mounting system that should work in theory to keep two magnets in place and perfectly still. and came up with a way to restrain them to 7 inches of levitation max. I've managed to find out that pull force is equal to repel force in magnets (you can correct me if i got it wrong there). So my base magnet weighs about 2.44 pounds with a repel/pull force of 149 pounds. my top magnet weighs 0.233 ounces with a repel/pull force of 33 pounds. Here's my question: shouldn't I be able to add 10 pounds of weight (non magnetic material) to the top magnet without increasing the overall weight of the base magnet? simply because the base magnet is so much stronger? is the restrained distance of levitation itself a problem? magnet specs at bottom of this post.

WHY I WOULD LIKE TO KNOW: i know the top magnet should be considered weightless if it was to levitate perfectly at its maximum repel height. (Found that out through a lot of experimentation, turns out someone had a post stating that already on another thread). I had to come up with a mounting system because i almost lost a damn finger trying to work with these magnets and i realized they have to be perfectly centered above one another and remain still for even a slight chance for this to work i think . No i'm not a scientist, or a engineering major, i'm an art major trying to figure something out thats waaaay out of my field. Yes I have spent countless hours trying to understand magnetic force and diamagnetics to funnel the magnetic repel force in a more controlled direction. But I'm just not a physics master. However I do enjoy learning and believe we are all students of weird science in life.

As you described it, The two magnets are repelling each other and restricted mechanically at 7 inches.

I see no difference between adding weight on top of the thing restricting movement and adding it to the magnet. If the distance is mechanically maintained at 7 inches, that determines the force on the lower magnet. I'm not completely sure that is what you are asking.

What force do you measure between h the magnets repelling at 7 inches?

magnet guy
you said that your base magnet was 2.4 lb, then y0u said 2.4 oz ...

Let's hope it is for curiousity sake. If it is about getting free energy, a kind of perpetual motion mill, we're in for big trouble. As a kid I thought magnetism could be switched on and off without incurring any power. I never knew to lift a mass of 1 kg using electromagnets not only do you need a bit more than 10 Joules but additional energy to cover loses through friction and field resistance not to mention the need to maintain a force of 10 newtons for as long as the object is suspended in space. how i wish we could switch off and on higgs boson at will.
